About this ASN.

Updated  ·  Confidence: High

AS28 is a legacy allocation held under RIPE (not ARIN) by the Deutsches Zentrum für Luft- und Raumfahrt e.V. (DLR, the German Aerospace Center) in Cologne — a clear region surprise, since the low ASN might suggest a US site but this is in fact Germany's national aerospace research center, the only non-ARIN, non-US entry in this block. RFC 1020/1166 list AS28 as "DFVLR-SYS" (the DFVLR Telecommunications Institute), and DFVLR (Deutsche Forschungs- und Versuchsanstalt für Luft- und Raumfahrt) is the predecessor name of today's DLR; the ARIN RDAP shell for AS28 simply points to the RIPE NCC block, confirming RIPE is authoritative. The RIPE aut-num is tagged status LEGACY, maintained by DFN (the German research network). The ASN appears dormant at the object level — no hosted domains, peers, upstreams, or downstreams are visible — so its live announcing status should be verified before treating it as active. The RIPE object's 2002-08-21 creation date is a database-migration date, not the original 1980s assignment. For triage, do not assume US ownership from the low ASN; this is German aerospace research space under RIPE. No notable public abuse signal was found as of June 2026.
